Are you sure you really need a Regex for this? Why not just check the length of the string?

I'm not going to give you the full solution, but I'll give you a close one, and you can finish it:

.{9,20}

I recommend you read up on regular expressions so you don't need to ask such basic questions.

.{6,30}

Dot (.) matches any character except line breaks (\n), unless you specify RegexOptions.Singleline in the Regex constructor, in which case it matches every single character. And it always matches carriage return (\r), just in case you were wondering. And 6,30 is the range of characters to match using the match expression to the left of the range (in the above case, that would be dot). So, the above expression matches between 6 and 30 characters (of any type, except for \n depending on how you construct the Regex), inclusive.
